About this task
Procedure
1. Read the safety information that begins on “Safety” on page vii and
“Installation guidelines” on page 33.
2. Turn off the server and peripheral devices and disconnect the power cords and
all external cables, if necessary.
3. Remove the cover (see “Removing the cover” on page 36).
4.
Remove the air baffle (see “Removing the air baffle” on page 37).
5. Carefully open the retaining clips on each end of the DIMM connector and
remove the DIMM.
Attention: To avoid breaking the retaining clips or damaging the DIMM
connectors, open and close the clips gently.
6. Touch the static-protective package that contains the DIMM to any unpainted
metal surface on the outside of the server. Then, remove the DIMM from the
package.
7.
Turn the DIMM so that the alignment slot align correctly with the alignment
tab.
8. Insert the DIMM into the connector by aligning the edges of the DIMM with
the slots at the ends of the DIMM connector (see “System-board optional-device
connectors” on page 32 for the locations of the DIMM connectors).
9. Firmly press the DIMM straight down into the connector by applying pressure
on both ends of the DIMM simultaneously. The retaining clips snap into the
locked position when the DIMM is firmly seated in the connector.
Note: If there is a gap between the DIMM and the retaining clips, the DIMM
has not been correctly inserted; open the retaining clips, remove the DIMM,
and then reinsert it.
